Answer:
B
Explanation:
The the word 'advantageous' is a throw off, it just means whichever point gives someone an advantage.
B explains simply that teens get something out of it, in this case socializing with other teens their age.
You have to look at the phrasing of language used, like for example, 'that playing video games is advantageous', implies that the person who is gaining the advantage is the person playing the games, not critics or the video games themselves, which rules out options A and C.
But on another note, it could also be D because the act of playing games can mean others who are not playing it profit from it, such as the parents and young people.
But I would put B down and complain to whoever had set the question about how vague it is. Haha.
I hope this helps. :)
